z/VM Overview

The z/VM hypervisor extends the capabilities of z Systems and LinuxONE
environments from the standpoint of sharing hardware assets,
virtualization facilities, an communication resources. Together with
IBM Wave, the comprehensive administration solution for z/VM-based
virtual Linux server environments, z/VM makes it easier to receive the
maximum value from large-scale virtual server hosting on z Systems and
LinuxONE. This includes software and personnel savings, operational
efficiency, power savings, and optimal qualities of service. This
virtualization technology is designed to enable organizations to run
hundreds to thousands of Linux servers on a single IBM z Systems or
LinuxONE server with the highest degrees of efficiency and elasticity,
running with other z Systems operating systems, such as z/OS and
z/VSE, or as a large-scale enterprise LinuxONE server solution.

With z/VM and its Linux infrastructure, you can reduce the time
between deciding on the acquisition of new servers and then
implementing them because new servers can be easily deployed in a
matter of minutes. With this powerful capability, you can launch new
products and services without the exhaustive planning for purchasing,
installing, and configuring new hardware and software that can be
associated with conventional discrete hardware servers. Development
groups that need test environments that are built and rebuilt rapidly
to enable them to efficiently deliver their projects, handling change
management in the process, can also benefit from this unique
advantage.

IBM z/VM V6.4 delivers:

Support for up to 2 TB of memory that enables:

Higher levels of workload consolidation

Considerable growth in memory-intensive applications

Superior levels of elasticity for workload spikes

Increased efficiency with HyperPAV paging that takes advantage of IBM
DS8000 features to increase the bandwidth for paging and allow for
more efficient memory management of over- committed workloads
